Problems solved by technology

At present, most oil-immersed transformers use heat sinks or heat sinks plus fans to dissipate heat. This heat dissipation method will make the oil-immersed transformer too large and the heat dissipation effect is not ideal.

Abstract

The invention relates to the technical field of transformers, and discloses an oil-immersed transformer cooling device. The oil-immersed transformer cooling device comprises an oil tank, two corrugated sheet sets and a cooling assembly, wherein a cooling liquid inlet and a cooling liquid outlet are formed in a tank body of the oil tank, the two corrugated sheet sets are arranged on the two opposite side walls of the oil tank respectively, each corrugated sheet set comprises a plurality of corrugated sheets, the corrugated sheets on the same side are arranged at intervals and in parallel and are communicated with an inner cavity of the oil tank, the cooling assembly comprises a plurality of cooling pipes, cooling liquid circulates in the cooling pipes, the multiple cooling pipes are arranged in the multiple corrugated sheets in a one-to-one correspondence mode, and the two ends of each cooling pipe communicate with a cooling liquid inlet and a cooling liquid outlet in oil correspondingly. The oil-immersed transformer cooling device is compact in structure, small in occupied area and high in heat dissipation efficiency.

Description

Technical field [0001] The present invention relates to the field of transformers, and more particularly to an oil immersion transformer cooling device. Background technique [0002] Immersion transformers act as main devices running in power systems, and whether it is safe and stable. Oil-immersive transformers are in operation, the energy consumption in the core and windings is converted to heat, ensuring the normal operating temperature of the oil immersion transformer, is of great significance for the life and stability operation of the oil immersion transformer. At present, most of the oil-immersed transformer heat dissipates by heat sink or heat sink, which makes the oil-immersed transformer are too large, and the heat dissipation effect is not ideal. Inventive content [0003] Based on the above, an object of the present invention is to provide an oil immersion transformer cooling device with a compact structure, small area, and high heat dissipation efficiency. [0004] ...
